Status of the Bridle Shiner, Notropis bifrenatus, in Canada
Bibliographic record
Abstract
The Bridle Shiner is a small minnow that is restricted to the Atlantic drainage of eastern North America.In Canada, it is found in lowland areas of eastern Ontario and southwestern Québec where it is generally rare.It is usually found associated with aquatic vegetation where it breeds and finds food and protection from predators.Although it appears to be stable in a few areas, the Bridle Shiner has apparently declined in most of the river systems that have been recently resurveyed.The status of this species in many other waters where it has been captured is unknown because there have been no surveys there since the 1970s.Its decline is probably as a result of poor water quality, high turbidity, and decrease in suitable aquatic vegetation particularly in small rivers of the agricultural zone.It is recommended that the Bridle Shiner be classified as Vulnerable in Canada.Le méné d@'herbe est un petit cyprinidé dont la répartition est restreinte au bassin de drainage Atlantique de 1' Amérique du Nord.Au Canada, sa présence a été rapportée dans les basses terres de |'est de l'Ontario et du sud-ouest du Québec; il est généralement rare.Ce cyprin est associé a la végétation aquatique, au sein de laquelle il se reproduit, s'alimente et s'abrite.La présence de cette espéce n'a été reconfirmée que dans une minorité de cours d'eau ou sections de cours d'eau ayant été l' objet d'inventaires répétés au cours des 50 derniéres années.Son déclin est probablement relié a la dégradation de la qualité de l'eau, a l'accroissement de la turbidité et 4 une diminution de la disponibilité des herbiers aquatiques propices a l'espéce, et ce particuliérement dans les petits cours d'eau en zone agricole.Au Canada, le méné d'herbe devrait étre considéré comme une espéce vulnérable.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
